Abstract

The aim of the work was to trace the water method of sowing grain crops using modernized methods and techniques of basic soil cultivation in dry farming conditions on light chestnut soils of the Lower Volga. In the course of the study, the result was obtained that the largest supply of productive moisture accumulated on the options of deep loosening when using a tool of minimum strip cultivation with working bodies of ROPA - 144.1 mm of moisture by the time of sowing of spring grain crops. This is due to the better state of the agrophysical properties of the soil - duty cycle, permeability. A small resource of moisture was recorded on the option with moldboard plowing with a PN-4-35 plow to a depth of 0.20-0.22 m (117.5 mm). There is reason to believe that this option has high soil density and reduced porosity.
